Application filed December 16, 1911. Serial No. 666,165.

To all whom it may concern Be it known that I, JOHN T. HARNETT, acitizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented new and usefulImprovements in Combination Bath Traps, WVastes, and Overflows, of whichthe following is a specification.

My invention relates to new and useful improvements in combination bathtrap, waste and over-flow, and has for its object to provide anexceedingly simple and effective device of this character which will bestrong in construction, inexpensive in the cost of manufacture, easilymounted in position and quickly taken apart when necessary.

Another object of the invention is to produce a trap, waste andover-flow for bath tubs combined into one fixture, which will be mountedbeneath the tub but above the floor, thus doing away with a number ofwipe joints.

A further object of the invention is to provide a single trap for thewaste and overflow which may be readily and quickly reached should itbecome clogged.

WVith these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction in detail, referring by numeral to the accompanyingdrawing forming a part of this specification, in which Figure 1, is aside elevation of the bath trap, waste and over-flow made in accordancewith my improvement. Fig. 2, a plan view thereof, and Fig. 3, a verticalsectional view thereof.

In carrying out my invention as here embodied, 2 represents a casingpreferably cylindrical in shape, open at the upper end and provided withinternal threads 3, into which is threaded a cover 4:, having anexternally threaded integral collar 5, provided with an opening 6passing entirely through the cover 4. Upon the collar 5 is threaded anut 7 carrying a resilient ring 8, said resilient ring expanding as thenut 7 is threaded upon the collar 5 causing said resilient ring tofirmly grip the over-flow pipe 9. The upper end of the over-flow pipe 9,is securely mounted in the bath tub and carries a screen or shield 10while the lower end thereof enters the casing 2 through the opening 6 inthe cover 4:.

11 denotes the Waste pipe having an external flange 12, which under-liesthe bottom of the bath tub and said pipe is provided with internalthreads 13 into which is threaded the cap 14:, provided with externalthreads 15 and carrying an external flange 16 adapted to over-lie thebottom of the bath tub, it being understood that the cap is open topermit the passage of the waste water. The Waste pipe 11 is joined toone end of the inlet pipe 17 and held in place by a nut 18, the oppositeend of said inlet pipe 17 being mounted in the casing 2, near the bottomthereof, thus making a connection between said casing and the waste pipe11. Leading from the casing 2, in proximity to the bottom, is an outletpipe 19, the outer end thereof being joined to the elbow or trap pipe 20by the nut 21.

In practice the fixture being mounted above the floor, it may be easilyinstalled and without the use of wipe joints and when it becomesclogged, the casing may be opened to remove the foreign matter bybacking off the nut 7 and unthreading the cover 4 from the casing 2.

Of course, I do not wish to be limited to the exact details ofconstruction here shown as these may be varied within the limits of theappended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new anduseful, is

1. In a device of the character stated, a casing having a closed bottomand an open top, a cap threaded into the top of the casing for closingthe same, an inlet pipe leading from the bottom of the bath tub to oneside of the casing adjacent its lower end, an outlet pipe leading fromthe opposite side of the casing in alinement with the inlet pipe, a trapconnected with the outlet pipe outside of the casing, an overflow pipeleading from the upper portion of the bath tub, and projecting throught-he cap, and means for cletachably securing said over-flow pipe in thecap.

2. In a combination trap, waste and overflow, a casing open at the topand provided with internal threads, a cover having an integralexternally threaded collar and provided with an opening, an over-flowpipe leading from the bath tub, and mounted in the opening in the cover,a nut surrounding said pipe, and threaded upon the collar, an inlet pipecarried by the casing, a Waste pipe 5 having a flange adapted to overliethe bottom of the tub, a nut for joining the Waste pipe to the inletpipe, an outlet pipe leading from the casing, in alinement With theinlet pipe, and a trap connected With the outlet 10 pipe outside of thecasing, whereby the interior of the casing is left unobstructed for theremoval of foreign matter.

In testimony whereof, I have hereunto aifixed my signature in thepresence of two subscribing Witnesses.

JOHN T. HARNETT.
